Battery Cycle Monitor

The Battery Cycle Monitor feature provides detailed data each time the batteries experience a dis- charge event. By keeping track of cycles imposed on the battery, the Operator has an indication of consumption, amount of useful life left on the batteries, and an early warning to service and/or replace the batteries. The data can be retrieved from the front panel LCD, remote terminal interface, or a modem connection.

The Battery Cycle Monitor screen can be selected from the Battery Management screen (See Figure 83). The default setting is set to ENABLE.
